老年人残根的临床保留效果分析

Clinical evaluation of preservation effect of residual roots in the aged

目的:对老年人残根临床保留效果进行分析,评估可保留进行固定修复的残根的牙周手术效果。方法:对402例586颗残根临床可保留性进行分析,对于121颗位于龈下的残根,根据残根根面位置分成3组进行不同牙周手术治疗。术后4周常规修复,随访1年。结果:586颗老年人残根中,148(25.26%)颗被用于覆盖义齿,314(53.58%)颗被用于固定义齿修复。对于牙槽嵴顶距残根断面>3mm的残根,牙龈切除术效果较好;对于<3mm的残根,牙冠延长术效果较好(P<0.01)。结论:老年人多数残根是可以保留用于活动或固定修复。老年人的残根在选择适合的牙周手术治疗后,再进行固定修复是可行的。

Objective：To evaluate clinical preservation effect and the effect of periodontal surgical therapy of residual roots in the aged. Methods：A total of 586 residual roots in 402 cases were included in this study. 121residual roots with subgingival defect which had received by root canal therapy were divided into three groups underwent different periodontal surgical methods and restored 4 weeks after operation and followed-up for one year. Results：148（25.26%） residual roots were used as overdenture abutment,314（53.58%） teeth residual roots were used as fixed restoration. Gingivectomy and crown lengthening surgery could achieve better results in the distance 3 mm and3 mm respectively according to the distance between the margin of residual root and bone crest（P0.01） . Conclusions：A lot of residual roots in the aged could be reserved for removable or fixed denture. Residual roots in the aged can be restored with fixed restoration after sound periodontal surgical therapy.
